Warning shots aren’t always an option. This former MMA fighter has already stabbed a police officer to death, but for some reason, the responding officers try to bring him in alive… at first. Once the warning shots fail, they go for a more lethal option. This video shows why real life isn’t like the movies, and one bullet isn’t always enough to stop an attacker. It is unbelievable how much damage the human body can take before finally ending the fight.
